Earlier we wrote about the security issue which the new iOS 7 is having iOS7 - How to Bypass Lock screen. Apple released a small update (18.2 MB) which will upgrade from iOS7 to iOS 7.0.2 and which will fix the passcode Screen Lock bypass issue.
So if you are using the iOS 7 we suggest you to upgrade it to iOS 7.0.2.
Screenshots
Now the passcode screen will not allow you to access the control center.
